Expanded Metal Angle Bead Reinforces Plastering Corner Expanded metal angle bead is used to produce a truly straight corner which protects and reinforces plaster with its expanded wings that offered by expanded metal construction. It helps protect plaster where it is most vulnerable, widely used in new build or refurbishment projects. As we all know that in building construction or when the project is completed, the plaster or rendered corners are easily damaged easily, which brings much trouble. Using appropriate angle beads can form a true straight arris that won't easily crack because the expanded metal wings ensure that the bead is securely anchored in the corner depth of plaster on either side of the arris, so the angle bead has another name - expanded metal corner bead. Feature Stainless steel or galvanized treatment for corrosion resistance. The exact size of the acute angle design disperses the force by the impact. Angle beads shorten the construction time and save the cost. Various sizes for choice and quality guaranteed. Specification Material: galvanized steel, stainless steel. Standard angle bead (internal use): 47 mm wing as standard angle bead, available in 2.4 m, 2.7 m, 2.8 m, 3 m, for 10 mm - 20 mm plaster depths. Stainless steel angle bead (external use): available in 3 m, to suit 16 mm - 20 mm plaster depths.
